BUCKLE.

Application filed .April 27, 1927. Serial No.` 186,922.

My invention relates to buckles and particularly to that type composedof two members, one member pivotally secured upon the other and onemember designated as the tongue member, both members jointly operatingto clamp between them the strap to which the buckle may be applied.

v My invention has for its object the manufacture of a buckle in whichthe parts composing it are preferably of cast metal and co-operate tohold a strap, with which the buckle is adapted to Vbe used, by clamping'the strap at both ends of the buckle.

Referring to the drawings in which similar numerals indicate identicalparts- Figure 1 is a plan view of my buckle applied to a strap. Figure 2is a section on the line 2 2 of Figure l. Figure 3 is a plan view of thebuckle. Figure 4' is a bottom plan view of Figure 3. Figure 5 is a sideelevation of the buckle, and Figure G is a side view of one member ofthe buckle.

The members 1 and 2 are, preferably, cast, the member 1 consisting ofside bars 3 and 4. connected by transverse bars 5, 6 and 7, the latterbar having a denticulated outer edge a. The tongue member 2 is formed ofside bars 8 and 9 connected by transverse bars 10 and 11. IThe bar 11 ofthe tongue member 2, when the buckle is assembled, is located forwardlyof the denticulated bar 7 a sufficient distance to provide space forreception of the running part 19 of the strap, and has an upwardinclination so as to clamp the strap against the teeth of the bar 7. Theside bars 3 and 4 of the member 1 are extended upwardly, intermediatetheir length, to form bearings 12 and 13 in which are pivotally securedtrunnions 14 and 15 integral with the bar 10.

In the manufacture of thermember 1 the bearings 12 and 13 are cast open,as shown in Figure 6, to receive the trunnions 14 and 15, and when thelatter are in place, I close the bearings by bending the extensions 16and 17 toward each other over the trunnions andso secure the members 1and 2 together to form a completed buckle.

In using my buckle the end of a strap is passed around the bar 6 andunder the bar 5 back upon itself where it is riveted or otherwisesecured. The running part 19 of the strap is passed upwardly between thebar 11 and the denticulated bar 7 and over the bar 10 and then under thebar 5 between theA latter and the fixed part 18fof the strap. It will benoticed that the bar 5, of the part 1, and the bar 10 of the tonguemember 2 are substantially inthe same horizontal plane as more clearlyshown in Figure 5, and the bar 6 is in a lower plane but above thebottom line of the part 1 as shown more clearly in Figure 2, so thatvitfollows that when-a strain is brought upon the strap, the part 2 willclamp the running part of the strap against the teeth of the bar 7, andas the strain will seek a straight line, the continued pull, acting uponthe bar 11, with an upward stress, will exert its `force to rock y thepart 1 so that the bar 5 will clamp the running part of the strapbetween the bar Y 5 and the part 18, the fixed part of the strap, sothat the ruiming part 19 is thereby clamped against slipping and is heldwith a force which is added to by any increase in the strain of thepull.

I haveproduced a buckle which in continued experiments has proven ofgreat value, particularly when it is used in a position where a positivesecuring of the strap against slipping is absolutely necessary and whichcan be relied upon for its efficiency under any conditions. What I claimis` 1. A buckle, composed of a main member ing bearings projectingupwardly from the sides thereof, the tongue member pivotally permit thepassage of a strap upwardly between the forward ends of said members, atransverse bar on said main member rearwardly of said bearings below theplane thereof and above the plane of the lower side of the main memberand to which one end of a strap is to be secured, a transverse bar onthe rear of the main member in substantially the plane of said bearingsrand under which the running part of a strap is to be passed, said tonguemember and main member co-operating to clamp the running part of thestrap at both ends of the buckle.

2. A buckle, composed of a main member and a tongue member, the mainmember having bearings projecting upwardly from the sides thereof, atransverse denticulated bar atthe forward end of said member, a tonguemember pivotally mounted in said bearings and a tongue member, the mainmember havand extending below and forwardh of the main member, atransverse bur on the tongue member forwardly of the @lenti-eu-v laterlbar and cof-operating therewith to clamp a strap passed between. Heem, atrams verse bar on said main member rearwardly of said bearings andbelow the plane there" of and above the plane of the lower side of themain member and 0 which lam e'nd Of aI l0 strap is to be secured,` and atransverse bar on the rear of the mai-n member in substantially theplane' of said bearings :m under which the running part of a strap islto be passed and damped. simultaneously against the part of the strapAseeured to't'beV bar rear Wardof the bearings with and by the clampngaction of the tongue member and the denticulated bar.
